| (54) | Wireless handoffs between multiple wireless networks |
| (57) Methods of communicating from a wireless communications device are described, the
method comprising: supporting a call over a first network that uses a first access
technology or a second network that uses a second access technology to a remote communications
device; and handing off the call from the first network to the second network by establishing
a connection to the second network to support the call with the remote communications
device, conferencing the wireless communications device into the call over the second
network, and terminating a connection to the first network that was previously supporting
the call with the remote communications device, wherein the connection to the second
network is established in response to signaling from a network entity supporting a
connection between the wireless and remote communication devices over the first network;
the signaling from the network entity configured by the network entity to request
that the wireless communications device establish the connection;, wherein the handoff
of the call from the first network to the second network is transparent to a user
on the call.
